apply_graph_theme: Apply multiple DiagrammeR global graph attributes

In Matherion/rock: Reproducible Open Coding Kit

Description

Apply multiple DiagrammeR global graph attributes

Usage

apply_graph_theme(graph, ...)

Arguments

graph	The DiagrammeR::DiagrammeR graph to apply the attributes to.
...	One or more character vectors of length three, where the first element is the attribute, the second the value, and the third, the attribute type (graph, node, or edge).

Value

The DiagrammeR::DiagrammeR graph.

Examples

exampleSource <- '
---
codes:
  -
    id: parentCode
    label: Parent code
    children:
      -
        id: childCode1
      -
        id: childCode2
  -
    id: childCode3
    label: Child Code
    parentId: parentCode
    children: [grandChild1, grandChild2]
---
';
parsedSource <-
  parse_source(text=exampleSource);
miniGraph <-
  apply_graph_theme(data.tree::ToDiagrammeRGraph(parsedSource$deductiveCodeTrees),
                    c("color", "#0000AA", "node"),
                    c("shape", "triangle", "node"),
                    c("fontcolor", "#FF0000", "node"));
